In this system, a low-cost model, with sub-control keyboard SP8050 alternative Haeundae controller cable so that the system becomes more simple. SP8050 also remote control switch (SP2000 series) and Quad. There are alarm switch function, when there is an alarm, the scene the camera can automatically switch out the alarm, and recording. In terms of cost, is lower than using the system host / matrix switcher system. Small model system was much to be equipped with the system host and is not strictly limited. In general, when the comprehensive monitoring system to achieve the number of cameras more than 3 to 4, you can consider using a small system host. Although the use of multiple single-channel controller or a multi-channel (eg, 4 or 6-channel) controllers can be implemented to control the full range of the camera, but that more needed to control the amount of cable (at least one in every way 10-pin cable), and the cable length will be too long (voltage drop caused by long-term resistance may lead to the head and the motorized lens movement does not even slow motion), the system will look messy. In general, the panel will increase the cost of using the system of the monitoring system, which is due to host system than the average cost of the switch is high, and with the support of the front-end decoder price is higher than the average single-channel controller. But wiring consideration is the use of a bus connected between each decoder and the system host, so the small number of cable systems (only a two-core communication cable). In addition, the integrated system has alarm host large detector interface, you can easily burglar alarm system and TV monitoring system integration in one. When the detector alarms, the host can be automatically switched to the main monitor screen camera site alarm occurs in the footage. Figure 1-5 shows the structure of the system host a small television monitoring system. CCTV closed-circuit monitoring system: security technology to prevent system is an important component is an advanced, highly integrated system of prevention capabilities, it can be a remote camera and its accessories (lens, pan, etc.) directly Watch all the circumstances of the monitored sites, can the situation be monitored sites at a glance. Meanwhile, TV monitoring system also can be linked with other security technology to guard against running anti-theft alarm system and other systems to prevent the ability to be more powerful. Components: CCTV surveillance system is mainly analog television monitoring system, the abbreviation CCTV. General monitoring system consists of front-end equipment, transmission equipment, the rear end of the device which controls the display of three parts. Wherein the front-end equipment including power equipment and imaging equipment in two parts; transmission equipment into the coaxial cable, twisted pair, fiber optic three categories; backend device video distribution devices, storage devices, display devices, operating equipment of four parts. Monitor The type of TV monitoring systems often need to monitor the sound on the site (for example: bank teller system monitoring system), so the system structure, the entire television monitoring system consists of images and sounds of these two parts. Due to the increased collection and transmission of sound signals, in a sense, the size of the system is equivalent to doubling than pure fixed video surveillance systems, but also in the transfer process should ensure the synchronization of picture and sound signals. For simple one structure (Camera - Recorder - Monitor), as long as the increase in monitor head and audio transmission line can be displayed along with the video and audio signals, monitor and record. For switching monitoring system, you need to configure the video and audio sync switches, video and audio signals which can be from multiple input switching and outputs the selected video and corresponding audio signal. System configuration and the part of the function monitoring system consists of the following components: 1, video capture system 2, PTZ camera control system 3, signal transmission system 4, a video processing system Video Capture System: Video Capture System cameras primarily by observation point composition, mainly to complete the video signal acquisition. From the existing 58 high-performance color digital camera components. The main video collection for each collection point. Where 20 cameras with PTZ device can be realized mainly to monitor a wider area. PTZ camera control system: PTZ camera control system mainly consists of head and controller. For complete change and observation points in the monitoring center of the enlarged image observation position of robotic cameras, reduction processing. Signal transmission system: In this system, the signal transmission system includes the transmission, transmission line video signal and control signal power signal composed of three parts. Video processing system: a video processing system is mainly to complete the long-distance transmission of digital video signal processing, display the image signal stored image signal and image signal. The system uses four sets of 16-channel DVR and remote transmission system to achieve display for all collection points, recording and playback and remote viewing. System features: 1, using the most advanced digital compression technology (MPEG-4), through computer processing to achieve the image display, storage, playback and remote transmission 2, each display, storage, playback can reach 6.25 / sec 3, display resolution up to 768 * 576, storage, playback resolution up to 384 * 2884, can be stored on the hard disk of each observation point observation. 5, it can record the playback history stored in the storage process. 6, history has a time stamp 7, highly integrated system on a computer can achieve full operational 8, all with WINDOWS interface, simple and flexible 9, through PSTN, ISDN, LAN, WAN achieve remote image browsing. Comprehensive monitoring based comprehensive monitoring system is the aforementioned sentinel surveillance system in the fixed-focus lens into electric zoom, and can increase the full range of head movement up and down (inside the head has two motors), so that each monitoring point The camera can be scanned up and down, and it can also be equipped with the lens focal length within a certain range (monitoring the scene can be pulled away or propulsion). Obviously, heads and motorized lens action requires the host controller or the system is controlled with a decoder. The easiest comprehensive monitoring system compared with the easiest point monitoring system in the front adds a full range of head and motorized zoom lenses, an increase in the control room of a controller, such as the SP3801, additional front-end to the control room need more laid over one core (10-pin or 12-pin) control cable. Taking a small garment factory monitoring system, for example, in its garment workshop installed two omnidirectional camera, the director of the office in the configuration of a normal TV, a switch and two controllers, when plant long workshop to understand the situation, simply by switching control of a camera picture selection and operation of the controller by the camera panning the entire surveillance scene can also be fixed on a local monitor. In practice, it does not necessarily make each monitoring point are configured by the full range, usually only in the monitoring system of a few special monitoring point was equipped with a full range of equipment. For example, in the aforementioned sentinel surveillance systems in a guest house, also may consider the case of fixed cameras monitor the parking lot instead omnidirectional camera (replacing the motorized zoom lens and increase full range of head), in the control room and then adding a control device, so that you can expand the scope of the parking lot surveillance, and both can be scanned on the entire parking lot, a local can also be monitored. Especially when advancing the lens, you can also see the license plate number. The simplest type fixed point monitoring system is in place to monitor the scene point the camera (the camera is connected with fixed focus lens), the video signal transmitted through the coaxial cable to the control room monitors. For example, at the gate small plants placed a video camera, and the video signal is transmitted through the coaxial cable into the factory office monitor (or TV), the manager can see who work late or leave early, leave whether they carry the goods when the factory plant. If re-configure a VCR, you can also monitor the picture recorded for later retrieval verification. This simple sentinel surveillance system for a variety of applications. When the number of cameras is more, it can be monitored via mux, Quad or system host. In the name of a foreign company headquarters, for example, has repeatedly lost the headquarters of high-end laptop, then all 12 outlets of its floors are installed fixed cameras, and is equipped with three sets of four Quad and a 24-hour real-time video recorder, effectively put an end to the above-mentioned phenomenon theft. A guest house also adopted this simple sentinel surveillance system. This is at both ends of 1-6 floor room passage of the installation of a fixed black and white camera, with a large entrance foyer, back door, parking lot and other four monitoring points total of 16 cameras, and then configure a 16 Quad, a 29-inch large-screen TV and a 24-hour recorders constitute a complete monitoring system. When monitoring points will increase the size of the system becomes large, but if there is no other additional equipment and requirements, such monitoring system is still attributed to a simple point system, closed-circuit television monitoring system in a supermarket, for example, since the supermarket large business area (upper and lower levels a total of about 16,000 square meters), more shelves, installed a total of 48 sentinel monochrome camera. This 48 camera signals are divided into three groups received a corresponding 16 Quad 17-inch black and white monitor and 24-hour recorders (actual project in the supermarket an additional anti-theft alarm system and a public broadcasting / background music system, here omitted).
